i Application filed May 17,

i To all whom it may concern:

'Be it known that I, ANDnns CARL AUGUST ZEUT EN, residing at Silkeborg, Denmark, and whose post-oiiiceaddress is Silkeborg, in the Kingdom of Denmark, have invented certain new and useful Improvements in or i Relating to Churns or Churn-Kneaders; and

particularly .churn-kneaders, in which the margarin is separated fromits e'mulsionby direct cooling with water. The invention is characterized in that, as soon as the "crystallization has begun, the water is supplied automatically, each supply being uniform, no attention or practice being necessary on the part of the workman, and in that there 'is no possibility of mistake which could damage the consistency of the margarin.

The drawing shows one 'form of construction, by way of example, 1n which the automatic water supply takes place.,through the rear supporting-axle of a churn-kneader.

Figure 1 is a vertical sectional view partly in elevation showing the controlling-device of the water-valve. J v

Fig; 2 is a' similar view showing another manner of disposing the valvef I Fig. 3 is a detail view of the mechanism for operating the valve. I I

The water is conducted .into the churn 1 of which the rear wall only is shown in Fig. 1, through a pipe 2, a pipe-coupling 3, and a pipe 5 having a bearing in the'hollow supporting-axle 4, at the outer end of which pipe there is a valve 6 in the shape of an acute cone. By means of a ratchet-wheel 8 and pawl 9 the screw-threaded valve-rod 7 can be screwed out through a nut 10 in the pipe-coupling by turning the lever 11 of the ratchet. This turning movement is effected by means of a slotted fork-arm 12 on a revoluble axle 13 slidably and rotatably mounted in the bracket member 16, a pin 11 of the lever 11 slidably engaging the slot. The axle also carries another arm 14, which lies in the path of the pin 15 on the churn 1, the pin 15 engaging the arm 14 upon each revolution ofthe churn, turning the arm 12 and the ratchet lever and thereby gradually 1916.

forthareof no significance tothe invention, I

and they can be altered in many ways ad-'-" mltt ng of thesame results,.n'amely, that the water is automatically supplled from. the

beginning and always in a uniformm'anner.

. In the form of-constructionshown in Fig.

2 the valve 6 has its seat at the inner end of the p1pe'5, and the conical'shape of the valve and its seat is such that a part of the water, meansof the pressure existing in" I the pipe 5 will be squirted all the way over to the front wall of the churn 1, so that the I cooling effect is equally distributed throughout the whole churn, which is of importance.

To'the same end, the pipe 5 shown in Fig. 1
